Bulgarian coincidence

We (Karon and Chris) travelled to Bulgaria to buy a property by arrangement with an estate agent in Bulgaria. On the day we travelled there another couple (Karen and Chris) walked into the same estate agent on spec. looking to buy a property. The estate agent had thought this a strange occurance and told us about it. Two days later we met each other briefly at the estate agents and then waved our goodbyes as we set off on our separate ways to view properties. After 3 days of viewings we bought a house in a quiet little village and went back to the estate agents office to deal with the paperwork. Whilst there we met the other couple who were also sorting out paperwork for the house they were buying. The four of us went for a coffee and to tell each other about our exciting purchases. As we looked at the area map to see where we had each bought houses we found that we had chosen to buy in villages next to each other, our houses were about two miles from each other. As we chatted further we found that we had all come from the West Country, Devon and Cornwall. Our homes in the UK were 45 minutes distant from each other. 3 of the four of us worked in social care. We had never met each other in the UK. We have now been friends for 7 years.
